Blue Orchids

[Jorge_Burrito]

No, not sad orchids, but orchids with blue flowers. I have not really seen any except perhaps some Vandas that are more purple blue than blue blue. Anybody have any they can think of? If not, is their a scientific reason? Seems like flowers can be found in just about every other color pretty easily.

P.S. have been a lurker for awhile and just want to thank you all for all the great advice on the board.
